All-optical spatial light modulator for reconfigurable silicon photonic circuits
Roman Bruck,Kevin Vynck,Philippe Lalanne,Ben Mills,David J. Thomson,Goran Z. Mashanovich,Graham T. Reed,Otto L. Muskens +7 more
TL;DR: In this article, the authors demonstrate all-optical wavefront shaping in integrated silicon-on-insulator photonic devices by modifying the spatial refractive index profile of the device employing ultraviolet pulsed laser excitation.

Silicon Photonics Rectangular Universal Interferometer
Daniel Pérez,Ivana Gasulla,Francisco Javier Fraile,Lee Crudgington,David J. Thomson,Ali Z. Khokhar,Ke Li,Wei Cao,Goran Z. Mashanovich,José Capmany +9 more
TL;DR: In this article, the implementation of a fixed rectangular universal interferometer using a reconfigurable hexagonal waveguide mesh circuit is described, and a suitable adaptation synthesis algorithm tailored to this mesh configuration is provided.
Journal ArticleDOI
Dual-etch apodised grating couplers for efficient fibre-chip coupling near 1310 nm wavelength.
TL;DR: For the first time, the combination of dual-etch and apodization design approaches are demonstrated which may achieve a coupling efficiency of 85% (-0.7 dB) on fibre-chip grating couplers operating around 1310 nm.
